Figure 7.

PCA loadings plots of the pJRES NMR spectra of canine urine. (A) Unscaled data, (B) autoscaled data, (C) Pareto scaled data, (D) glog transformed
data. The plots represent the loadings perpendicular to the decision line calculated
by using LDA on each of the scaled data sets. The 5 largest bins in each plot have
each been tested as potential biomarkers to discriminate between the two classes.
Key: (solid circle) bin is not significantly different; (*) p < 0.05; (**) p < 0.01;
(***) p < 0.001.
